I second that! I have tried sleeping for 8 hours and I just end up feeling sluggish all day. Less than 6 hours has the same effect. 6 hours just happens to hit the sweet spot.

I would suggest meditating anytime in the day. I dont believe that it specifically has to be in the morning. It could be a placebo but just sitting still for a bit does some to help.

I don't know how true this is, but it's something I've found true for myself... I've read (or heard) that your sleep cycle is 90 minutes down to deep sleep and back, so it's best to get up after some multiple of 90 minutes because that's when you'll have cycled back to the lightest sleep.

So typically I either get 6 hours or 7.5 hours of sleep a night, though if I ended up getting 3 or 4.5 one night I'll sometimes try to get 9 the next night. If I can't get at least 3 hours of sleep, I just stay up.

So it's possible the problem with 8 hours is that you're trying to wake up in the middle of a cycle and thus the sluggishness. Or maybe I'm just spreading pseudo-science.

I have heard that too but never really got down to testing it out. In fact I have resigned to the fact that when it comes to sleep to each their own.

For eg I have experienced better quality of sleep after taking ZMA ( I weight train ). But I have heard anecdotes where people have said that its just a placebo.

I take Magnesium every day, it has helped my sleep tremendously. I am more relaxed and less stressed during the day, too. It's like I am 10 years younger.

A what time do you take the magnesium?

That's basically how http://sleepyti.me works.
